Rebuild / Conversion Parts R380 / LT77?

Keep me right please people - recently bought an honest but very weary 'F' plate Ninety that deserves a of love, as an unfinished project it came with a ton of parts and I'm now doing a load of sleuthing to work out what the plan was with the previous owner.

I have the following:

FTC4108 Shorty Bell Housing

I also have:

FTC5062 R380 Pinion Shaft
FTC1438 LT77 Front Cover
FTC4173 + FTC4174 Fork Pivot
FTC2957 Clutch Fork Kit
UTJ100210 Release Bearing

This appears to be a mixed bag of R380 and LT77 but is there a compatibility here that I can't see maybe with the plan of an LT77 to R380 conversion with the shorty bellhousing?

Thanks for any advice and I looked before I asked but couldn't find any existing threads which answered this. BTW, the parts are not in line with my build therefore available if of any interest.

The short bellhousing can be fitted to the 2.5 N/A, 2.5 petrol and the 200 TDI engines, anywhere the 4 Cyl LT77 is standard so that an R380 gearbox can be fitted.

All of the other bits are also for the R380 (or at least will fit between the gearbox and the clutch).

All those bits you have would fit with my LR Flywheel and LOF clutch I am selling .... (just saying )
